Slope control console

Claim 1

A slope control console comprising: a case adapted to be mounted on a machine such as a paver or a grader; a sensor within the case for sensing the inclination of the case relative to a predetermined slope, said sensor being movable with the case for sensing the inclination of the case relative to said predetermined slope and being rotatable about a horizontal axis relative to the case for changing said predetermined slope within a specified range; means for adjusting the sensitivity of the sensor extending from the sensor and being rotatable therewith; an opening in said case for providing ready access to said adjustment means, said opening being of sufficient size to permit manual operation of the sensitivity adjustment means with the sensor at any rotational position relative to the case within said specified range; a cover for closing said opening; means for indicating the inclination of said sensor relative to said case; means for effecting rotation of said sensor throughout its said specified range to a desired position relative to the case for establishing said predetermined slope; and a manually operable gear train constituting said means for effecting rotation of the sensor, said gear train interconnecting the indicating means and the sensor and being operable simultaneously to effect rotation of the sensor relative to the case and movement of the indicating means with said indicating means being moved through a relatively large increment of rotation in response to said sensor being rotated through a relatively small increment of rotation, said gear train having a first gear constituting a driver manually operable from the exterior of said case, at least one intermediate gear, and a last gear interconnected with said sensor for rotation of said sensor about said horizontal axis in response to operation of the gear train, said indicating means comprising indicia on the face of said intermediate gear viewable from the exterior of the case for registering the inclination of the sensor relative to the case, said intermediate gear rotating through an angle substantially greater than the angle through which saiD sensor is rotated in response to operation of the gear train to provide said large increment of movement of the indicating means relative to said small increment of rotation of the sensor.
